ALEXANDER STILES, OF MARTINSVILLE, INDIANA.

NOISE AND LIGHTNING ARRESTER FOR TELEPHONE-WIRES.

SPECIFICATION forming part of Letters Patent No. 735,839, dated August11, 1903.

Application filed March 6, I903. Serial No. 146,440. (No model.)

To all whom it may concern:

Be it known that I, ALEXANDER STILES, a citizen of the United States,residing at Martinsville, in the county of Morgan and State of Indiana,have invented certain new and useful Improvements in Noise and LightningArresters for Telephone-Wires, of which the following is aspecification.

This invention relates to improvements in telephone-lines; and theobject is to arrest the vibrations of the wires, due to wind and othernoise-producing causes foreign to the sou nd-waves from thetelephone-transmitter, and to provide means during a thunder-storm forbreaking the line and grounding the leading-in Wire outside of thebuilding to prevent damage from lightning.

I accomplish the objects of the invention by the mechanism illustratedin the accompanying drawings, in which Figure 1 is a perspective view ofmy invention in operative position in a closed circuit; Fig. 2, atransverse section of same on the line 2 2 of Fig.1; Fig. 3, alongitudinal section of Fig. 1; Fig. 4, a side view of the plug; andFig. 5, a like view of the spring-clasp for holding the plug, the saidparts being shown detached from each other.

Like letters of reference indicate like parts throughout the severalviews of the drawings.

A and B represent the ends of a divided telephone-line wire which are tobe connected by means of my invention.

0 is a clasp, of spring metal, preferably brass or steel, having an eyeD at one end through which the end B is threaded and the end broughtback and twisted to the body of the wire, as shown. The thinned cornersof the clasp adjacent to the loop in the wire B are bent over againstthe wire, as shown at d d, to make the joint rigid between the clasp andwire-that is, so a rotary or torsional movement of the wire will carrythe clasp with it in a corresponding movement; The end opposite the eyehas the longitudinal split f to receive the end F of the plug E. Theopposite end of the plug is perforated, and through this perforation thewire A is threaded and the end of the wire twisted fast to the body ofthe wire in the same manner as described for the end B. The adjacentcorners of the plug are bent over upon the loop of wire A in the groundbelow.

the manner described for wire B and for the same reason. The corners ofthe end F are slightly rounded, and the end is tapering, as shown. Theouter portion of the jaws formed by the split f in the clasp 0 haveoutwardlydiverging inner faces to facilitate the insertion of the plug,and to insure an extended contact between the clasp and plug, and toincrease the efficiency of the clamp I prefer to expand the innerportion of the split, as shown in Figs. 3 and 5, so the closing of thejaws will not be interfered with by contact at these inner parts beforethey are tightened upon the plug. The sides of the tapering plug will befiat, with the exception of the corners, as above mentioned, and theinner faces of the jaws will follow the contour of the walls of theplug, being bent inwardly at the edges of the jaws, as clearly shown inFig. 2. This construction holds the plug firmly within the clasp, sothat when one of said parts is revolubly moved the other must move inlike manner.

The telephone-wire running into a building is provided with theabove-described detachable connection. have a cable G attached to it,which drops down within reach of a person standing on When a storm isapproaching, the electrical connection is' broken by pulling down oncable G, which separates the line wire, and the disconnected endsdropping down to earth grounds the wires.- 1 have also found by extendeduse that my invention successfully arrests the annoying vibrationscaused by the blowing of the wires by the wind and other noise-producingagencies.

Having thus fully described myinvention, whatI claim as new, and wish tosecure by Let ters Patent, is-

A divided wire, a plug secu red to one end of the wire, having atapering end with rounded corners opposite the fastening end, a claspsecured to the other wire end comprising a bar splitlongitudinally atthe end opposite its attachment to the wire end, said split forming jawswhich are oblique for a distance from their outer ends and haveinwardly-bent edges for such distance and which are spread apart fromsaid oblique portions inwardly to prevent premature contact, said plugand One of the parts will clasp having thinned outer ends transverselyhand and seal, at Martinsville, Indiana, this perforated to receive therespective ends of 5th day of February, A. D. 1903. the divided wirewhich are looped throu h 1 e 1 said perforations and the sides of saidthinnzd ALEXANDER bTILES l Witnesses:

5 portions bent over upon the looped Wires to compel simultaneousrotation. J. E. OVERTON, In Witness whereof I have hereunto set my 1 J.W. MEELY.
